Filed: 1989-06-29
Abstract: PURPOSE:To attain an invariably legible gradational display even when a voltage value is varied by varying the ratio of a time of the application of a selected voltage to a signal electrode and a time of the application of a nonselected voltage according to a scanning voltage value, a selected voltage value, and a nonselected voltage value. CONSTITUTION:The output of a voltmeter 1 is inputted to a ROM 2 and a clock signal, on the other hand, is inputted to a counter 4 and converted into a waveform obtained by dividing one selected period by 64 and inputted to the ROM 2. The ROM 2 generates a signal waveform which determines a gradation pulse width with the signal of the counter 4 and the signal of an A/D converter. This waveform is sent to a driver IC for gradations through a flip- flop circuit 3 and a voltage waveform to be applied to a signal electrode is outputted according to the gradation level of a picture element. Therefore, the scanning voltage value, selected voltage, and nonselected voltage value are varied for control over transmissivity, the pulse width of gradations is set according to the voltage value and the legible gradational display is obtained.

Filed: 1992-06-25
Abstract: PURPOSE:To increase the amount of sintered products and prevent the occurrence of the breaking phenomenon by a method wherein the shelf board consisting of Si-SiC sintered body containing SiC and Si is given a thickness not exceeding a predetermined length of its diagonal line. CONSTITUTION:The size and thickness of a shelf board consisting of the Si-SiC sintered body containing SiC and Si are so controlled as to prevent the breakage thereof. Specifically, the board thickness is required to be at most 2.5% of the length of the diagonal line of the shelf board, preferably 2.0%. The more preferable board thickness is at most 1.0% but with the minimum limit of about 0.1%. If the board thickness goes below the minimum limit, there is the danger of the board breakage upon handling. It is also desirable that the shelf board be provided with slits 10-13, since the sporing resistance can be further improved. The Si-SiC sintered shelf board thus controlled in size and thickness is particularly excellent in the sporing resistance and free from the breaking phenomenon upon baking, thereby making avoidable accidents such as collapsing in a furnace.
